cross bars 16 16 and fixed to the front bars of said auxiliary frame are circularly curved side rails 17 whose diameters are somewhat larger than the total diameter of the drum and blanket 10 mounted thereon to form annular spaces 17 between the blanket and said rails. To the auxiliary frame are also fixed curved rails 18, which extend around and above the upper part of the drum and at their rear ends have attached to them a trough or chute 15 arranged in an inclined position with the lower end directed forwardly and terminating near the rear upper part of the drum. The upper part of the chute is supported on legs 15 and by lateral arms 15 fixed to the main frame.

The stencils, which are adapted to be fed by gravity from the chute 15 into the appa ratus, comprise each a comparatively narrow eylindrically curved metal member 14: (Fig. recessed longitudinally, as at 1 1' and a piece of oil or wax paper 14 containing the matter to be copied and Which is fastened to the inner face of the metal sheet 1 1 over the recess 14: the size of said recess and of said wax pa er 1 1 being made according to the text c esired to be copied. At each end, the inner face of the metal. sheet or member 14 is formed with a pair of transversely extending lugs or blocks 1 1 14 separated from one another and forming a recess or notch 14 between themselves. The stencils are adapted to be stacked in the chute to rest on one another with their lugs and extend longitudinally of the drum 0. The chute is formed with side walls 15 and a bottom 15 the free edges of said side walls being bent over the open front of said chute. The lower ends of the side walls 15 and the front part of the bottom 15 are cut away, as at 15 and 15, sufiiciently to expose the front edge of the lowermost one of the stencils stacked in the chute and one of the lugs at each end thereof. The rear part of the bottom 15 of the chute 15, as seen from Figs. 1 and 1, extends away from the drum in a somewhat downwardly inclined position, so that the stencils will be held thereon in a rearwardly and downwardly inclined position and be thereby prevented from falling out through the opening 15 in the bottom of the chute. The forward edge of the lowermost stencil will lie close to the drum and the notches 14 thereof be in the path of the pins or projections 12 of the blanket 10, which pins, when the drum is rotated .in the direction of the arrow 0:, will pass into the notches 14", and on engaging the forward lugs 14 pull said stencil out from the chute through the open parts 15 of the side wall 15 The stencil will then be lodged on the drum with the ends thereof resting on the end flanges c 0 of said drum and leaning with one end against a collar 0 of the latter (Fig. 3). As the drum continues its rotation in the same direction, the stencil 1 1 passes into the annular spaces 17 between the rails 17 and the blanket and is held by said rails 17 from falling off the drum. The printing or copying is effected in the same manner as with the rdinary stencil at the time the stencil passes over the roller 6, the roller pressing the recipient such as letter or envelope against the stencil lt and the latter against the ink-pad 13.

Fixed to the rear edge of the bottomof the chute are one or more downwardly pro-- jeeting rigid fingers 19, the lower ends of which are made to terminate close to the face of the drum 0 or blanket 10 and lie in the path of the front edge of the stencil 14 engaged by the drum.

lVhen during the rotation of the drum,

the stencil arrives close to the said fingers 19, the latter will engage the front edge thereof and as the drum continues to rcvolve, lift the stencil out of engagen'ient with the pins 1.2 of the blanket. The released stencil will then drop off the drum onto a suitable collecting means, such as a tray 20.

Fixed to the rear of the auxiliary frame at 21, is a shelf-like member or platform 21 extending longitudinally throughout the length of and at the rear of the drum. This platform has a rear wall 21 and sidewalls 21 and fixed to the latter are rigid posts 22 from the upper ends of which are tiltably suspended by arms 23 rearwardly inclined guide members 24. The forward ends of said members are connected by a cross member 24, which bears with a slight pressure against the drum 0 or the blanket 10, the

pressure being exerted by weak springs acting on the arms 23. The rear ends of the members 24., which project above the shelf 21, are bent in a downwardly and forwardly inclined position, and have attached to them below said shelf a bar or board 26, which extends immediately above the tray 20. The posts 22 are extended below the bottom of the shelf 21 and are formed with a cross piece 22 extending longitudinally of the drum. This cross piece 22 in conjunction with a second cross piece 27 fixed to the legs of the chute form supports for the removable tray 20.

hen a stencil, after the printing opera tion, is released by the rear ends of the bars 1'? and arrives at the cross bar 24", it pushes the latter rearwardly against the tension of the springs 25. ti 'hereby "he board 26 will be swung rearwardly and will displace the stencil or stencils that may have accumulated on the tray 20. 28 denotes a weighted guide or abutment, which may be movably supported on said tray and which will re tain the stencils dropping onto the tray in upstanding position and in order.

' carr the same alon with the drum;

IVhen it is desired to insert in copied or printed letters or circulars or on envelopes, names, addresses or other data, the letters, envelopes or other recipients of said print ing matter L are stacked on the tray or base J, whence they are adaptedto be fed byhand into the machine as usual. The chutev is filled with the stencils 1a in a pre .viou's'ly arranged order, so as to rest upon one another with the'lugs l l' extending forwardly: After fastening the blanket 10 to the drum in the aforedescribed manner, the latter is rotated by hand. As the pins 12 during the rotation of the drum in the direction of the arrow as arrive below the lowermost stencil, they enter the notches 14E thereof and on engaging thefront' lugs 1 pull sald stencil out from the chute and stencil, on passing over theroller e in cooperation with the ink-pad 13,. will produce.

the copying of the printing matter on the letter or envelope that happens to he be tween it and the roller 6; As the'rotation of the drum continues, the stencil rises at the rear :of' the drum and after its release from the guide rails 17 reaches the lingers 19, whichon engaging the front edge of said stencil, lift the latter from the drum,

permitting it to slide down onto the guide arm's Qatand thence drop-off onto the shelf 21 landing thereon on its rear edge, but by its own weight tumbling over forwardly and dropping down onto the tray between the cross piece 26 and the rest 28.

At the starting of. the printing or copy-v ing operation, the rest 28 is adapted to be close to the board 26, the space between them being smaller than the width of a stencil, so that when a stencil drops onto the tray, it will be retained on its edge leaning with its back against said rest. Each time a stencil rises .on the rear of the drum 0, it will in passing the arms 24: slightly swing the latter rearwardly in consequence of which the board 26 will shove the stencils accumulating between it and the rest 28 in the same direction making room for a new stencil. I

hen all stencils have been dropped out from the chute, the tray 20 can be removed and the stencils thereon, which in the afore' described manner have been arranged in their original order, can be dropped back into the chute for repeated use when desired. v I

In Figs. 8 and 9, I have shown a modified ink blanket 10. The same may be made of fabric with reinforced sheet metal edges 10 10 and have an ink-pad 13* adjustably fixed thereto. To this end, a sheet metal plate 10 is fixed to the metal edges of the blanket to extend transversely thereof. This plate is longitudinally slotted at 10".

' The The ink-pad proper 13 is fixed by gluing or otherwise to a sheet metal base lOflwhioh by stamping is formed with downwardly .extending flaps: 10 passing through the slot l0 and the freeends of which are bent ovento engage a second metal ends of the blank-et are ada-sted'to be hooked together by hook 11 and eyelet 11", after the blanket is mounted around the drum, as

the heretofore described blanket 10. By

making the ink-pad adjustable, the size of the' latter can be made just-large enough to cover the printing" matter on the stencil;

Va l -at I claim is 1.
